Using the Panchromatic band for water column correction to derive water depth and spectral bottom signature: Landsat 8 OLIP bandset used for this work Purple_1, Blue_2, Green_3, PAN_4, Red_5, NIR_6 and SWIR1_7 |
![]() TCC deglinted/smoothed with location of Profile Blue | ![]() TCC raw |
![]() Retrieved depth by the GREEN solution with location of Profile Blue | ![]() Retrieved depth by the PAN solution with location of Profile Blue |
![]() the GREEN solution on Profile Blue bands 1 and 2 versus GREEN the DTM profiles are shown in red | ![]() the PAN solution on Profile Blue bands 1, 2 and 3 versus PAN the DTM profiles are shown in red |
The GREEN solution yields poorly contrasted water column corrected bottom signatures: bottom typing shall be mainly be based on brightness | The PAN solution reveals more contrasted water column corrected bottom signatures: this enhances the potential for bottom typing |
